VEHICLE VENTILATOR.

Y Application led August 8, 1,925. Serial N'o. 48,948.

This invention relates toventilators for vehicles and is well adapted foruse'in closed automobiles, auto busses and 'street cars, for example. The primary object is to provide a ventilatorwhich may be easily regulated to vary the amount of air admitted there# through, whichwill allow a large dlscharge .without the admissionof rain or snow, land `which may be easily and cheaply Aconstructed.

Otherwise stated, the object is to provide a ventilator which' will' ventilation during wet and stormy weather and lwhich during fair weather maybe adjusted to furnish considerably greater ventilation. f

A vfeature of the invention is the provision of a hinged cap or cover member capableof being easily adjusted to different positions to vary vthe discharge. Another feature 1s theprovision in this cap of a great number of smallopenings whereby when currents of air are passed therethrough, countercurrents are minimized thereby securingV greater effective discharge than with a few large openings. AThe cap is preferably `so suplported that, Linder impactfof the limbvof Ya tree or like obstruction `in the way ofthe vehicle, it will swing downwardly against a resilient means, and when the obstruction V`is passed will .again assume its adjusted position. y

My ventilator preferably operates in conjunction with an opening in the roof of the vehicle body and'means such as a shutter may be employed beneath such an opening i to close it entirely when desired. A member opening is .positioned over the body` opening on the Outside. of the wall and to this baille member,y Ipreferably attach, as by means of a hingea cap,ar. ranged to be resiliently and adjustably supv ported at various heights; When the cap is in`V its closed position, discharge of air from the vehiclethrough the opening is having a restricted y provided for-by reason of anumber of per forations in the wallsV of the cap in offset Vrelation to the opening in the baille.

, Further features of the invention will 4rhereinafter a-ppearin the detailed description to follow,.whichrelates tothe accom- `trated the preferred formof the invention. rlhe vvessential characteristics will be sun/i1- thev drawings, Fig.

Referring in detail tothe' in di ating the aciers, represents a portion of the vehicle roof having an opening' therethrough indi-` called at B. Above the opening l have shown an inner cover or baffle member l having a sloping roof portion at 2 4and a restricted cent-ral opening A3, preferably square as shown, andhaving an upwardly extending brim portion 4. This member maybe cheaply made from stamped sheet material and wall A as by means of drawings and tion l2 'and a downwardly curved brim 13,

shown ascut away at intervals along its i edges at let in order that it may never become entirely closed at vits lower edges against the escape of water from within the cap and whereby when its lowered position, which serves toincrease the"ventilating action.y

jl have shown the s lopingroof portion of the cap as provided Vwith a great lnumber of small openings l5 preferably arranged close together as shown. I havefound that the discharge 'afforded bylsuch a large number of small openings is greater than that of a smaller number of larger openings or a inglelarge opening having even greater total area, and the reason for this, l believe to be that countercurrents suon as Vwould tend to obstruct the path' ofjair leaving the vehicle through the ventilator, are eliminated. The discharge openings l5 as indicated Vin l5 Vareover the i of thel baffle member willrbe deflected .by this roof portion onto Fig. 3; a

the4 shutter arvarious parts by suitablechar! The cap has a sloping roof por- 1 inclined `roof portion 2j l at all times and then' through the openingsv the root oit the vehicle body. Then the guard is in raised position, as tor instance in Fig. 5, the brim l extending above the root portion 2 of the battle is so disposed that even in a driving storm there will be very little, it any, rain likely to he driven under the brim of the cap and into the opening 3.

To provide for adjustably andl resiliently raising the cap, I preferably employ a link and lever arrangement, the members ot' which may be pivoted to the battle and cap respectively and which are arranged to be operated from within the vehicle by means of a knob and screw extending into a nut carried by the lever. Such an arrangen'ient may comprise a lever 2O pivoted at 21 to a bracket 22 secured to a portion of the brim 4: of the inner cover. The outer arm of th-e lever pivotally carries a link 24 which is also pivoted at 25 to a bracket shown as mounted on the root ot the cap. The lever 20, intermediate ot its ends carries a trunnioned nut 26 into which is threaded a screw 27. rl`he shank 28 of the screw slidably engages a support carried by the body wall, the support in this case being shutter members 30 and 31 to be later described.

lVithin the vehicle the screw knob 29 which it will be seen may ated to turn the screw, thus causing the trunnioned nut and its lever arm 20 to move up or down to adj ustably position the cap 10.

'By reason ot the cap being hinged to the 1oof at its forward edge and having the constant openings 14 and the variable opening when inclined, the movement ot the vehicle causes a strong rearward drafttrom under the cap which thus rapidly carries away air from the interior ot the vehicle. The adjustment ot the cap increases or reduces the amount ot this rearward draft but the openings 14 provide for such draft even though the cap is entirely closed as shown in Fig. 2.

Surrounding the shank o't the screw, I have shown a compression spring 33 which bears against a portion of the shutter member 30 at its lower end and which may be retained against upward expansion by a washer 34e and a pin passing through the screw. It will be readily understood that when the cap is in raised position it may be forced downwardly against the spring independently of the nut and screw, as tor instance when the cap contacts with the projecting limb of a tree. Under ordinary conditions the lspring will hold the cap in the desired adjusted position.

To limit the litt of the cap as well as to prevent the screw 27 trom becoming entirely disengaged trom the nut 26, I have provided a stop indicated at 20 arranged in the embodiment shown to strike a portion ot the bracket 22 when the cap is raised to the position shown in Fig. 5. It will be seen that when this projection 2Oa has engaged may carry a i. be oper.

the bracket no turther tipping of; the cap is possible, but `further turning ot the knob will compress the spring and the knob will, upon being further turned, project inwardly into the body of the vehicle. This move ment and the added stress against turning will advise the operator that the cap has been raised to its limit.

In order to close the opening l entirely it desired, I may employ a shutter arrangement. which as shown. comprises an annular plate (previously designated 3l), havingl sector shaped holes 3G through it, and a cooperating rotatable closure plate (previously designated 30) adapted to ovcrlie these openings This closure plate. which may be in the iorm ot a Maltese cross, and rotatably mounted on the shank ot the screw 28, and lies within a recess 23T formed by an overcut portion o't the member 3l and the slightly overhanging edge Ot the root ot' the vehicle. Vilhen this cross is rotated, the arms 3S may con'ipletely or partially close the passages a't't'orded by the holes 1N). A. depending lug 89 rigid with one ot the arms and extending through one ot these holes 36. may serve as an operating means for turning the plate.

It will be seen from the above description, that I have provided a ventilator which may be easily and cheaply constructed. which may be mounted in a compact space in the rooi.1 ot a vehicle, and which is so arranged as to secure enough ventilation for the safety ot the passengers in wet and stormy weather without admitting the undesirable weather elements into the interior of the vehicle body and which in fair weather may be adjusted for securing considerably greater ventilation to provide tor the comfort ot' the passengers without attendant drafts.

I am a 'are that the device is capable ot considerable modification while keeping within the spirit ot my invention and do not theretore wish to be limited to unessential details.

The ventilator may be used in various ways not above mentioned. tor example. when used on the root ot a vehicle. it niav be inclined either 'forwardly or rearwardlv., depending on its position relative to the body. it being sometimes desirable to have the cap arranged to incline vtorwardlv when positioned at the forward portion'ot' the body. in which case currents of air will readily pass into the body` while when it positioned at the rear ol the bod;v if. better to incline the cap to the rear so that the currents of air admitted by the torwardly inclined cap or caps at the front may be more readily discharged.
